Stove top espresso maker

My wife has an old stove top espresso maker. We are trying to find out how old. It is shaped like an upside down L with the water going in the taller end with a screw on knob on top. The filter is on the little end. With the cup under it. The name on it is, Vesuviana Brevettata. Any takers

Vesuviana Brevettata

Yes, I had one of those. Well as far as I know they were manufatured starting in the 50's. I bought one "new" in the late 80's. Same design,
I don't know if they still make them. But they look really cool.
